(CNN) - Top McCain adviser Steve Schmidt said Monday that newly-minted Republican VP candidate Sarah Palin informed John McCain of her daughter's pregnancy in one of their "private conversations" last week.

McCain aides insist the Arizona Republican already knew about the pregnancy prior to that conversation, having found out earlier during the lengthy vetting process.
"She was very upfront about it," one aide said.
Speaking with reporters, Schmidt also said McCain expected the pregnancy would eventually become public, as did Palin.
"Obviously people would know because she’s going to have a baby that she was pregnant," Schmidt said. "What we want to see happen is the privacy of Governor Palin’s daughter respected. And that’s what Senator McCain wants."
